GUIDE son ROLLING MILLS.

Application filed March 10, 1920. Serial No. 364,669.

T 0 all whom it may concern:

Be itknown that I, ELBERT'H. CARROLL, a citizen of the United States. residingat Worcester, in th county of Worcester and Commonwealth of Massachusetts, have in-' for rolling mills, and more specifically to the means for supporting and retaining said guides in operative relation to therolls. The invention contemplates a novel con struction and arrangement of parts, whereby, with the use of a single retaining device, the guide, irrespective of its adjustment, is held in a position adapted at all times to resist effectually the various strains that are setup in operation. The above and other objects are attained by the construction hereinafter described. reference being had to the accompanying drawings, in wh1ch Fig. 1 is a vertical sectional view of a roll housing equipped with entrance and delivery guides that are retained in position according to the method contemplated by the invention.

Fig.2 is a view in front elevation of one of the transverse supporting bars to which the guides are secured.

Fig. 3 is a fragmentary horizontal sectional view illustrating the wedges for adjusting a guide, the section being taken on the line 33 of Fig. 1.

Like reference characters refer to like parts in both figures.

Referring to Fig. 1, there is shown a roll housing 1 of'ordinary construction, which provides journals for the cooperating rolls 2 and 3. For directing the metal-into the pass provided by said rolls, and for guiding the metal delivered from said pass. the con struction provides the usual entrance and delivery guides 4 and 5 which. as herein shown, are supported on transversely extending bars 6 and 7 respectively. The bars 6 and 7 are supported by the housing 1 in any suitable manner; as shown in Fig. 2, the supporting bar 6 is provided at its ends with flanges 8 and 9. that have holes 10 and 11 for retaining bolts, not shown, which enter the opposite sides of the housing 1 and are adjustable therein in the usual manner to vary the height of the supporting bar.

The mode of securing the guides 4 and 5 to th bars 6 and 7 is the gist of the present invention; since the construction employed for this purpose is the same for both guides, it will be necessary to describe it in connection with only one. of them. As herein shown. each bar 6 and 7 provides two substantially horizontal bearing surfaces 12 and 13 to receive similar surfaces on the bottom of the guide. these surfaces being spaced apart. one at the inner and the other at the outer portion of the guide, so that adequate resistance is provided against any tendency of the guide to tip'or twist about a horizontal axis. Each bar is further provided with 'a substantially vertical shoulder 14 adapted to cooperate with a similar shoulder 15 on the corresponding guide in order to prevent cndwise outward movement of said guide. Between the shoulders 14 and 15 are adapted to be inserted suitable wedges, or the like, as shown at 16. Figs. 1 and 3 in order to secure longitudinal adjustment of the guide toward and from the rolls. It will thus be seen that each guide is adapted to bear against the supporting bar on three surfaces, one of which is in a substantially vertical plane and the other two in substantially horizontal'planes. widely spaced apart; the

invention contemplates a single retaining and securing means for the guide that, while permitting the necessary ad ustments above describedfwill at the same time effectually resist any tendency of the guide to'shift with respect to any one or more of said three contactmg surfaces.

To this end each bar 6. 7 is cut away interiorly to provide an elongated, generally inclined. slot 17, which opens on the top of the bar between the surfaces 12 and 13, and extends through to the oblique surface 18 on the bottom-of the bar. This slot 17 serves for the passage of a retaining bolt 19 that is pivoted. or otherwise movably secured as shown at 20. to the under side of the guide,

with its other end adapted to project loosely through the opening that the slot'17 provides in the. lower inclined surface 18 of the bar.

The bolt 19 is thus constrained to hem an oblique or inclined position, relative to each of the. bearing surfaces 12, 13 and 14,

theconstruction being such that the guide retaining force exerted through the bolt 19 is the resultant of the pressures on all three of said surfaces. The draft on said. bolt to retain the guide in position may be produced in any well known manner, as for instance by a wedge 21 passing through a slot in the lower projecting ,end of the bolt, and bearing either against the surface 18, or

against a suitable interposed washer 22. The

non-rigid mounting of the bolt 19, as above described, permits the adjustment of the guide by means of the wedges 16 without in any Way affecting the efficiency of the re taining means, which, under all operating conditions, andunder all conditions of adjustment, exerts its retaining force, in a single direction, to secure'adequate pressures of the guide against the three bearing surfaces, two horizontal and one verticah of the bar.

I claim,

1. The combination with a rolling mill guide, of a support therefor providing a plurality of bearing surfaces for said guide in different planes, and a single guide retaining ineans, acting in a direction oblique to all of said bearing surfaces.

2. The combination with a rolling mill guide, of a support therefor providing spaced substantially horizontal bearing surfaces for said guide and a substantially verticalbearing surface for said guide, and retaining means exerting its force in a direction oblique to all of said bearing surfaces, for holding said guide against movement relative to said support.

3. The combination with a rolling mill guide, of a support therefor providing a plurality of bearing surfaces for said guide in different planes, and a single retaining bolt operable on said guide to produce pressure of same against all of said bearing surfaces, with the resultant of said pressures exerted in the axial line of said bolt.

4. The combination with a rolling mill guide and its support, of a retaining means extending from said guide through said support, and pivotally attached to said guide, to permit of different angular positions for said retaining means in the various positions of adjustment of said guide.

, 5. The combination with a rolling mill guide and its support, of means for adjusting said guide relative to said support, and a retaining bolt permanently attached to said guide for holding the same rigid with said support in any position of adjustment. said holtbeing free to accommodate itself to various positions of adjustment.

6. The combination with a rolling mill guide, of a support therefor, providing plurality of bearing surfaces for said guide in different planes, and a retaining bolt movably secured to said guide and extending through said support in a plane oblique to all of said bearing. surfaces.

7. The combination with a rolling mill guide, of a support therefor providing a plurality of bearing surfaces for said guide in different planes, means for adjusting said guide relative .to said support, and retaining means for said guide passing obliquelythrough said support, and operable on said guide to produce pressure of same against all of said bearing surfaces in every position of adjustment of said guide.
